DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called double floor in which a floor panel is supported at a predetermined height by a supporting leg, and after the level is adjusted, the supporting leg is prevented from rotating and the supporting leg is fixed.

[0002]

2. Description of the Related Art A conventional double floor of this type is shown in FIGS.
As shown in FIG. 1, a panel fitting 2 is provided on a floor panel 1 and a male thread of a support leg 3 is screwed into a female thread formed on the panel bracket 2 or a male thread formed at the upper and lower ends of the support leg 3. Is formed in a reverse screw. In each case, the height of the floor panel 1 from the concrete slab 10 can be adjusted, that is, the level can be adjusted. After the adjustment, the support legs 3 need to be fixed so that the height of the floor panel 1 does not change. Therefore, as shown in FIG.
An adhesive or an adhesive is applied to a male screw portion formed at the upper end of the support leg 3 to be screwed into the support leg 3, or the lock bolt 11 is screwed into the panel receiving member 2 as shown in FIG.

[0003]

In the method of applying an adhesive, it is not possible to readjust when the position of the floor panel is changed because the support legs are completely fixed. Suitable for re-adjustment when the floor panel position is changed, but when used for many years due to the small fixing force, the support legs rotate and the height of the floor panel changes, causing steps and rattling There was an inconvenience. In addition, when a lock bolt is used, there is a fixing force and re-adjustment is possible, but the screwing work when attaching the lock bolt is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a floor panel support leg fixing structure which can surely fix the support legs with a simple operation and can be readjusted.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention relates to a stopper provided with an engaging portion which has a restoring force or is plastically deformed by being engaged or press-fitted into a female screw portion of a panel receiving member. The tool was driven without screwing it from above the panel fitting until it came into contact with the support leg head.

[0006]

In the present invention, since the stopper is driven from above the panel receiving member, the operation is quicker than the screwing operation. Further, if the stopper comes into contact with the support leg head and engages with the female screw portion, the fixing force becomes sufficient. When readjusting, the support leg can be pulled out of the panel fitting and the stopper can be pressed from above to easily drop it off the panel fitting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a female thread portion 2A is formed in a panel fitting 2 fixed to a floor panel 1. The female screw portion 2A has a male screw portion 3 formed at the upper end of the support leg 3.
A is screwed in, and the height of the floor panel 1 is adjusted by this screwing amount. After the height is adjusted to a predetermined value, the support leg 3 is fixed to the panel fitting 2. The stopper 4 is driven from above the panel fitting 2 to fix the support leg 3. This stop 4
Has an engaging portion 4A as shown in FIG.
Has raised, the engaging portion (projection) 4A is adapted to engage the internally threaded portion 2A. At least this engaging portion ( protrusion ) 4A has a restoring force, and when driven into the female screw portion 2A from above, after exceeding the thread, it is restored and engaged with the thread groove. . The stopper 4 is formed from a thin metal material.

[0009] Figures 3 and stop 4 shown in FIG. 4, the engaging portions 4
Has an outer peripheral edge portion as B, the engaging portion several places of notches 4C
4B , and these outer peripheral portions also have a restoring force, and are preferably formed of a thin metal material .

When the stopper 4 is formed of a metal material, the stopper 4 is attracted to a tool 5 having magnetic force, and the stopper 4 is inserted from above the panel receiving member 2 into the female screw 2A as shown in FIG. To work quickly.

When the position of the floor panel 1 is to be changed and readjusted, the support leg 3 is removed from the panel fitting 2 and the tool 5
The stopper 4 can be easily dropped from the panel receiving member 2 by driving such a member as to penetrate the female screw portion 2A.

[0012] fastener 4 illustrated in FIGS. 6 and 7 are formed from a plastic material, Yes to form the engaging portion 4B made of an outer peripheral edge portion over several stages in the axial direction on the outer circumference, these outer peripheral edge It is plastically deformed and engages with the female screw portion 2A. Also, a hole 4E is formed at the center so that a driver or the like can be easily inserted and driven.

The stopper 4 shown in FIGS. 8 and 9 is an elastic body,
For example, the stopper 4 is made of rubber, foam resin, or the like, and engages with the female screw 2A, or the stopper 4 is press-fitted into the female screw 2A and remains in the female screw 2A. This stop
The tool 4 has an engaging portion 4B formed of a one-step outer peripheral edge on the outer periphery.
It has been achieved.

[0014]

As described in the foregoing, according to the present invention, the panel receiving brackets of the internal thread portion to be engaged or pressed has a restoring force or a stop panel supports having an engaging portion capable of plastic deformation Screw it in from above the bracket until it touches the support leg head.
Since implanted without a fixed work support legs also quick and easy to, fixing force after typing a stop also becomes sufficient ones. Further, in the case of re-adjustment after changing the position of the floor panel, if the support leg is detached from the panel receiving member and the stopper is pressed from above, the stopper easily falls off the panel receiving member.
